NI 9862 Hardware Overview

The NI 9862 has one full-featured CAN port that is isolated from
the other modules in the system. The port has a Bosch DCAN
CAN controller that is CAN 2.0B-compatible and fully supports
both 11-bit and 29-bit identifiers. The port also has an NXP
TJA1041AT High-Speed CAN transceiver that is fully
compatible with the ISO 11898 standard and supports baud rates
up to 1 Mbps.
